程序启动testNG硒测试冻结

Question

当以编程方式使用testNG启动硒测试时，该过程冻结。所有测试都成功，但是该过程不会结束并且不会返回任何退出代码。

示例

Main.java

package com.example;

import org.testng.TestNG;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlSuite;
import org.testng.xml.XmlTest;

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        TestNG testNG = new TestNG();
        List<XmlSuite> xmlSuites = new ArrayList<>();

        XmlSuite xmlSuite = new XmlSuite();

        List<XmlTest> xmlTestList = new ArrayList<>();
        XmlTest xmlTest = new XmlTest(xmlSuite);

        List<XmlClass> xmlClassList = new ArrayList<>();
        xmlClassList.add(new XmlClass(TestOne.class));
        xmlTest.setXmlClasses(xmlClassList);
        xmlTestList.add(xmlTest);

        xmlSuite.setTests(xmlTestList);
        xmlSuites.add(xmlSuite);
        testNG.setXmlSuites(xmlSuites);
        testNG.run();
    }
}

TestOne.java

package com.example;

import io.github.bonigarcia.wdm.WebDriverManager;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Test;

public class TestOne {

    private WebDriver webDriver;

    @BeforeSuite
    public void prepare() {
        WebDriverManager.chromedriver().setup();
        this.webDriver = new ChromeDriver();
    }

    @Test
    public void testOne() {
        webDriver.get("http://google.com/");
    }

    @AfterSuite
    public void shutdown() {
        if (webDriver != null) {
            webDriver.close();
        }
    }
}

启动时

但是过程没有结束

Debug和Streis并没有太大帮助。发现AsyncHttpTimer挂起，它检查localhost上的端口

问题出在硒的Alpha版本中

github https://github.com/SeleniumHQ/selenium/issues/8159上有问题>

过渡到3稳定版解决了问题
